(2004): The Supremes nullify it, saying Newdow doesn't have standing.
2010: 9th Circuit Court of Appeals rules the Pledge constitutional. (200 page decision)
'Under god' is "a reference to the historical and religious traditions of our country, not a personal affirmation through prayer or invocation that the speaker believes in God." And the Pledge is an optional patriotic exercise.
[Similarly, 'In God We Trust' on our coinage is "of a patriotic or ceremonial
character and bears no true resemblance to a governmental
sponsorship of a religious exercise." (only a 15 pager!)]
I'm not really torqued about this. Especially since the courts keep reminding us that these are merely ceremonial utterances that don't really mean anything other than 'Yay America!'
